I was assuming that the utility function contained a bunch of data
regarding the external environment.
Otherwise, one can assume the computer C1 contains a utility function
U, and also a dataset D giving info regarding the external

At some point, when you find the time, it would be interesting if you
would post a purely mathematical formulation of the question that you
are thinking about. I am interested in such things, and I believe
that Shane Legg, who is a PhD student working with Juergen Schmidhuber
(and a former Webmind and A2I2 staff member) is also on this list (if
not, I'm sure he's on the AGI list); and Shane is even more interested
in thinking about such things...
